27. Let staticFields be a new empty List.
28. For each ClassElement e in order from elements,
a. If IsStatic of e is false, then
...
b. Else,
i. Let field be the result of performing PropertyDefinitionEvaluation for m ClassElementEvaluation for e with arguments F and false.
c. If field is an abrupt completion, then
...
d. If field is not empty,
i. If IsStatic of e is false, append field to instanceFields.
ii. Otherwise, append field to staticFields.
34. For each item fieldRecord in order from staticFields,
a. Perform ? DefineField(F, field).
...
DefineField(receiver, fieldRecord)
1. Assert: Type(receiver) is Object.
2. Assert: fieldRecord is a Record as created by ClassFieldDefinitionEvaluation.
3. Let name be fieldRecord.[[Name]].
4. Let initializer be fieldRecord.[[Initializer]].
5. If initializer is not empty, then
a. Let initValue be ? Call(initializer, receiver).
6. Else, let initValue be undefined.
7. If fieldRecord.[[IsAnonymousFunctionDefinition]] is true, then
a. Let hasNameProperty be ? HasOwnProperty(initValue, "name").
b. If hasNameProperty is false, perform SetFunctionName(initValue, fieldName).
8. If fieldName is a Private Name,
a. Perform ? PrivateFieldAdd(fieldName, receiver, initValue).
9. Else,
a. Assert: IsPropertyKey(fieldName) is true.
b. Perform ? CreateDataPropertyOrThrow(receiver, fieldName, initValue).
10. Return.
